Yvan Khaymovich, a specialized theoretical physicist, and John Baker, an astrophysicist who worked for twenty years at NASA’s main center in the United States (Maryland), one is Russian, the other American. They have recently moved to Toulouse as part of their recruitment at CNRS Occitanie in Toulouse. They explain the reasons for their decision.
John Baker, a 55-year-old astrophysicist, had been working for 20 years at NASA’s main center in the United States (Maryland). He has joined the Laboratory of 2 Infinities (CNRS-UT) and is conducting research on the Laser Interferometer Space Antenna, scheduled to launch in 2035.
Yvan Khaymovich, 40 years old, is a specialized research director in theoretical physics. He has not lived in the USA but has traveled around Europe since leaving Russia in 2013. He is involved in the “Choose France for Science” program. His research focuses on methods to prevent thermalization in quantum systems (like an ice cube in hot water keeping its shape and temperature instead of melting).
John Baker explains that they left the USA due to political and social reasons, particularly concerns over rights and safety for their family, including a transgender child. Yvan Khaymovich shares that some scientists have felt targeted by the Trump administration, citing examples from Columbia University.
Both scientists were connected to the “Choose France for Science” program through contacts and applications. John Baker considered Canada but chose France due to professional connections and a welcoming environment. Yvan Khaymovich learned about the program during a job selection process and decided on France due to political and research themes in Toulouse.
These professionals have made Toulouse their new home, seeking a secure and supportive environment for their scientific endeavors.
